I assume this is a 1911 and that by "tabs", you mean the leaf spring fingers? The leaf spring can be used to adjust the ratio of the first stage take-up to the let off to some extent. However, if you lighten the fingers too much, you become vulnerable to hammer following and disconnector malfunction. The right leaf affects the grip safety, but over or under-tensioning it will be felt on the other fingers.

Removing too much travel in the first stage of the trigger by flexing the trigger bow also increases the gun's vulnerability to hammer following, and should not be tried with a steel trigger stirrup or a wide, Goldcup style trigger. They have too much mass for best safety doing that. Besides, the first stage take up lets you gage your trigger tension. Overtravel is much more disturbing to me.

Boosting can settle a sear engagement in, but it has the most effect when there are still machining marks or is grinding surface roughness on the hammer hooks and sear to be worn in to self-fit. The pressure from boosting causes them to wear against each other, flattening the areas of high contact and kissing the areas of lower contact, thereby tending to spread contact out more evenly. Uneven engagement promotes creep.

You should test for hammer following after messing with a trigger. Remove the magazine from the gun. Lock the slide back. Pinch your right thumb and index finger over the ends of the pin at the bottom rear of the grip frame that holds the mainspring housing in place. Hold the gun balanced upright by that index finger and thumb. The muzzle will be angled up. Use the thumb and index finger of your left hand to depress the slide release. The slide should slap into battery without the hammer falling out of full cock.
